Spoke is generally in the shape of long strip, and after being connected with hub and rim, it can support the rim to keep it in the correct position, and at the same time, it can bear the force from all directions during riding, including impact force from ground and centripetal force during riding. During the preparation of spoke, it is generally molded by mold, and the two ends of spoke in length direction will extend outward for a distance, and the length of spoke needs to be accurately controlled, so the two ends of spoke need to be cut for a part, so that the length of spoke meets the requirements.

[0012] The rotating seat body comprises a rotating disc and a plurality of spoke fixing seats, each spoke fixing seat is fixedly arranged on the circumferential edge of the rotating disc along the circumferential direction opposite to the first axis, each spoke fixing seat on one rotating disc corresponds to each spoke fixing seat on the other rotating disc, and part of the spoke fixing part is arranged on each corresponding spoke fixing seat to form a complete spoke fixing part in the first direction.

[0014] Based on the first technical solution, the tenth technical solution is that the cutting assembly is movably arranged on the frame and adapted to reciprocate along a first direction.

[0016] Based on the first technical solution, the twelfth technical solution is that the frame comprises a cutting frame, the spoke fixture is arranged in the cutting frame, and the cutting frame is provided with an open waste outlet at the bottom.

[0017] Based on the first technical solution, the thirteenth technical solution further comprises a storage bin fixedly connected with the frame and adapted to store spokes to be cut.

[0018] As can be seen from the above description of the present application, compared with the prior art, the present application has the following beneficial effects:

[0019] The first technical solution provides a spoke cutting device, which comprises a frame, a spoke fixture and a cutting assembly. The spoke fixture comprises a rotating base and a fixture motor, the fixture motor can drive the rotating base to rotate around a first axis, and a spoke fixing portion is arranged on the rotating base, a spoke to be cut can be fixed in the spoke fixing portion and rotate with the rotating base around the first axis. The cutting assembly comprises two cutting devices, the two cutting devices are arranged along a first direction, and the cutting blades of the two cutting devices are respectively arranged on the two sides of the rotating base, wherein the cutting blades overlap the spoke fixing portion in a projection plane perpendicular to the first direction. Through the structure design that the cutting blades overlap the spoke fixing portion, when the spoke fixing portion is fixed with a spoke and the rotating base is driven to rotate by the fixture motor, the two ends of the spoke in the spoke fixing portion will pass through the positions of the cutting blades and be cut by the cutting blades. The relative positions of the two cutting blades and the spoke fixing portion can be determined in advance, and the relative positions of the two cutting blades and the spoke fixing portion will not change during the cutting process, so that spokes with a required length can be repeatedly obtained.

[0020] The spoke cutting equipment provided by this technical solution fixes the spokes to the spoke fixing part of the rotating base and makes the spoke fixing part rotate with the rotating base, so that the spokes can pass through the position of the cutting blade in the cutting device, thereby cutting off the excess part of the spokes by the cutting blade, thus completing the automated cutting of the spokes; the spoke cutting equipment has the advantages of high efficiency, accurate cutting position and small cutting error.

[0021] In technical solution two, the spoke fixing part is located on the circumferential edge of the rotating base, and the spoke fixing part is groove-shaped with a notch. When fixing the spoke, the spoke can be easily embedded into the groove-shaped spoke fixing part from the outer periphery of the rotating base. Since the spoke is fixed by embedding, the position where the spoke needs to be cut can be visually determined before embedding. After cutting, the cut spoke can be easily removed from the spoke fixing part. Furthermore, the notch faces outward relative to the first axis and is perpendicular to the first axis. During the process of embedding the spoke into the notch, the embedding direction of the spoke is easier to apply force, ensuring that the spoke is embedded into the spoke fixing part in the correct posture.

[0022] In technical solution three, a limiting component is provided, which includes two limiting devices, each including a stop bar with a limiting surface. Because the spoke fixing part is groove-shaped, while this structure facilitates embedding and fixing the spoke into the fixing part, when the spoke end is cut using a cutting device, the cutting blade contacting the spoke can cause it to bounce, resulting in an uneven cut surface. Therefore, in this technical solution, after the spoke enters the range of the limiting surface, the limiting surface limits the spoke in a first direction. This limiting can be either direct contact between the limiting surface and the spoke, or a very small gap between them. In both cases, the limiting surface prevents significant bounce of the spoke during the cutting process, effectively improving the problem of an uneven cut surface.

[0023] In technical solution four, the limiting device can reciprocate along the first direction, which facilitates the adjustment of the limiting position according to the required spoke length.

[0024] In technical solution five, the limiting component includes a first sliding device, which can drive the first mounting plate to move along a first direction via a first driving cylinder. The limiting device is fixed to the first mounting plate, thereby enabling the limiting device to reciprocate along the first direction.

[0025] In technical solution six, the spoke fixing part is also provided with a body section and a tightening section, which can be adapted to spokes with a specific shape. By the position of the tightening section on the spoke fixing part, when the spoke is correctly embedded and fixed in the spoke fixing part, the length of the part to be cut on the spoke to be cut can be directly limited.

[0026] In the seventh aspect, the rotating base comprises two rotating seat bodies, which can be adjusted in position in the first direction, and each of the two rotating seat bodies forms a part of the spoke fixing part, and the two parts cooperate to form a complete spoke fixing part. In this way, when the length of the cut spoke is adjusted, the position of the rotating seat bodies in the first direction is adjusted to change the distance between the two parts of the spoke fixing part, and then the total length of the complete spoke fixing part formed by cooperation is adjusted. When the cutting of the spoke is completed, the two ends of the spoke are exposed to the part of the spoke fixing seat, but since a gap can be formed between the two rotating seat bodies, the cut spoke can be easily taken out from the middle position, and efficient unloading of the cut spoke is realized.

[0027] In the eighth aspect, the rotating seat body comprises a rotating disc and a spoke fixing seat. The rotating disc can adopt a flat disc structure, so as to facilitate the rotation of the rotating base driven by the jig motor. The spoke fixing seat is convenient for arranging the spoke fixing part, and the size of the spoke fixing seat in the first direction can be different from that of the rotating disc in the first direction. The longer spoke fixing seat can make the arranged spoke fixing part have a longer length, so as to ensure that the spoke has a long enough part in contact with the spoke fixing part after being embedded and fixed to the spoke fixing part, thereby improving the stability of the spoke in the cutting process.

[0028] In the ninth aspect, a discharging plate is arranged. The discharging plate is inclined and extends and is provided with a discharging protrusion. During the rotation of the rotating base, the cut spoke passes through the discharging protrusion. The discharging protrusion applies force to the middle position of the cut spoke and pries the cut spoke from the spoke fixing part. The spoke separated from the spoke fixing part will move along the discharging plate. At this time, a material frame can be arranged at a proper position to collect the cut spoke.

[0029] In the tenth aspect, the cutting device in the cutting assembly can reciprocate in the first direction, so as to adjust the cutting position according to the length of the required spoke.

[0030] In the eleventh aspect, the cutting assembly comprises a second sliding device. The second driving cylinder can drive the second mounting plate to move in the first direction. The cutting device is fixed to the second mounting plate, so that the cutting device can reciprocate in the first direction.

[0031] In the twelfth aspect, an open waste port is arranged at the bottom of the cutting frame of the rack. The cut waste can be discharged from the waste port to the cutting frame.

[0032] In the thirteenth aspect, a storage bin is further arranged. The to-be-cut spoke can be first stored in the storage bin, so as to facilitate the feeding of the spoke jig. BRIEF DESCRIPTION OF DRAWINGS

[0051] Embodiment

[0052] The utility model embodiment relates to a spoke cutting equipment, and the spoke cutting equipment is used for cutting the excess length part of the length longer spoke semi-finished product, so that the length of the cut spoke meets the use requirement. Wherein, the spoke can be metal material or carbon fiber material, and the spoke of carbon fiber material is taken as an example for description in the embodiment.

[0053] Reference Figure 1The spoke cutting device includes a rack 10, a spoke jig 20, a cutting assembly 30, a limiting assembly 40, a blanking plate 51, a storage bin 52 and an electric control box 53.

[0054] Referring to Figure 1 , the rack 10 includes a base 11, a cutting frame 12, a protective baffle 13, a jig support 14, a cutting support 15, a limiting support 16 and a main support 17. The base 11 includes four legs, and the bottom of the leg is provided with an adjusting seat for adjusting the height of the base 11. The cutting frame 12 is fixedly arranged on the top of the base 11, and the cutting frame 12 is arranged as a box-shaped structure with a bottom wall and a side wall enclosed on the circumference. An open waste port 121 is arranged on the bottom wall of the cutting frame 12. Referring to Figure 2 , the bottom of the cutting frame 12 is also provided with a waste groove 122 extending backward and downward, and the top end of the waste groove 122 is communicated with the waste port 121. A waste collecting box can be arranged below the waste groove 122. The waste after cutting enters the waste groove 122 through the waste port 121, and then is guided into the waste collecting box through the waste groove 122, thereby completing the collection of the waste. The protective baffle 13 is fixed on the base 11 on the circumferential outer side of the cutting frame 12. The height of the protective baffle 13 is higher than the height of the side wall of the cutting frame 12, and the protective baffle 13 can substantially shield the spoke jig 20 on the circumference, and the protective baffle 13 is open on the front side. The storage bin 52 is fixed on the front side of the base 11. The storage bin 52 is a flat box-shaped member, and the internal cavity thereof can be used to store the spokes to be cut. The spokes to be cut can be conveniently taken from the storage bin 52 during feeding. The jig support 14, the cutting support 15, the limiting support 16 and the main support 17 will be described together in the following description of the spoke jig 20, the cutting assembly 30 and the limiting assembly 40. The electric control box 53 is arranged on the rear side of the base 11. The electric control box 53 is used to control the electrical devices in the spoke jig 20, the cutting assembly 30 and the limiting assembly 40, such as cylinders, motors and the like.

[0055] Referring to Figure 1 and Figure 3 , the spoke jig 20 includes a rotating base 21 and a jig motor 22. The rotating base 21 is rotatably mounted on the rack 10 about a first axis in a first direction, and at least one spoke fixing part 23 is arranged thereon. The jig motor 22 is in transmission connection with the rotating base 21 to drive the rotating base 21 to rotate. The spoke fixing part 23 extends along the first direction and is open at both ends to allow the spoke to be fixed and arranged and to make the both ends of the spoke to extend out of the spoke fixing part 23. The position of the spoke fixing part 23 on the rotating base 21 is configured to be suitable for rotating with the rotating base 21 about the first axis.

[0056] The spoke fixing part 23 is arranged on the circumferential edge of the rotating base 21 relative to the first axis, and is in a slot shape with a notch 234 for embedding and fixing the spoke, and the notch 234 is perpendicular to the first axis and outwardly faces the first axis. The spoke fixing part 23 includes a body segment 231 in the middle and tightening segments 232 at both ends in the first direction; the width of the tightening segment 232 is smaller than the width of the body segment 231. The rotating base 21 includes two rotating seat bodies 211 arranged in the first direction, and the rotating seat bodies 211 are slidably fixed to the rack 10 in the first direction; the spoke fixing part 23 is arranged on the two rotating seat bodies 211, and at both ends in the first direction, the spoke fixing part 23 is arranged on the two rotating seat bodies 211. The rotating seat body 211 includes a rotating disc 212 and a plurality of spoke fixing seats 213; each spoke fixing seat 213 is arranged on the circumferential edge of the rotating disc 212 in the circumferential direction relative to the first axis; in the two rotating seat bodies 211, each spoke fixing seat 213 on one rotating disc 212 corresponds to each spoke fixing seat 213 on the other rotating disc 212, and the corresponding two spoke fixing seats 213 are each provided with part of the spoke fixing part 23 to form a complete spoke fixing part 23 in the first direction.

[0057] Specifically, referring to Figure 3 and Figure 4 , both show the structure of the spoke jig 20. In the middle position of the cutting frame 12 of the rack 10, the jig support 14 is fixed on the bottom wall of the cutting frame 12 by bolts, and the position corresponds to the position of the waste port 121 on the cutting frame 12. The jig support 14 includes two vertically extending arms, which extend in the left-right direction, and it should be understood that the first direction referred to in the specification and claims is the left-right direction in this embodiment. A rotating bearing and a rotating shaft are also arranged on the two arms of the jig support 14, and a rotating base 21 is arranged through the rotating bearing and the rotating shaft. A jig motor 22 is fixed on one of the arms, and the output end of the jig motor 22 is connected to the rotating shaft to drive the rotating base 21 to rotate through the rotating shaft. The extension direction of the rotating shaft is the first direction, and the rotating axis of the rotating base 21 is the first axis, which also extends in the first direction. The jig motor 22 is also electrically connected to the electric control box 53 to control the operation of the jig motor 22 through the electric control box 53.

[0058] The spoke fixing part 23 is arranged on the rotating base 21, and extends along the first direction and is open at both ends. In the embodiment, the spoke fixing part 23 is arranged on the circumferential edge of the rotating base 21 relative to the first axis, that is, is arranged at the outermost position of the rotating base 21, and the spoke fixing part 23 is a groove-shaped structure with a notch 234. When fixing the spoke, the spoke can be conveniently inserted into the groove-shaped spoke fixing part 23 from the outer circumferential position of the rotating base 21, and since the spoke is fixed by insertion, the position of the spoke that needs to be cut can be intuitively determined before insertion, and after cutting is completed, the cut spoke can also be conveniently taken out of the spoke fixing part 23. Moreover, the notch 234 is perpendicular to the first axis, and during the process of inserting the spoke into the notch 234, the insertion direction of the spoke is more convenient to force, which can ensure that the spoke is inserted into the spoke fixing part 23 in the correct posture.

[0059] The rotating base 21 includes two rotating seat bodies 211 arranged along the first direction, and the two rotating seat bodies 211 are relatively independent components and are slidably fixed on the rotating shaft along the first direction. Specifically, a mounting ring for fixing the rotating seat body 211 can be arranged on the rotating shaft, the mounting ring is fixed around the rotating shaft, and has a locking surface facing the corresponding rotating seat body 211, the side surface of the rotating seat body 211 is in contact with the locking surface, and the rotating seat body 211 is locked to the threaded hole on the locking surface through the bolt penetrating along the first direction. The mounting ring can be fixed on the rotating shaft by clamping, when it is necessary to adjust the position of the rotating seat body 211, the mounting ring is loosened, then the position of the mounting ring on the rotating shaft is adjusted to a predetermined position, and finally the mounting ring is locked again to tightly clamp the rotating shaft. Each spoke fixing part 23 is divided into two parts and arranged on the two rotating seat bodies 211 correspondingly, and the two ends of the spoke fixing part 23 in the first direction are located on the two rotating seat bodies 211 respectively. It can be understood that since the two rotating seat bodies 211 are separated from each other, the part between the two rotating seat bodies 211 does not belong to the range of the spoke fixing part 23, and the spoke will be in a suspended state between the two rotating seat bodies 211 after being inserted into the spoke fixing part 23. In this way, when the length of the cut spoke is adjusted, the distance between the two parts of the spoke fixing part 23 arranged by the two rotating seat bodies 211 can be changed by adjusting the position of the rotating seat body 211 in the first direction, so as to adjust the total length of the complete spoke fixing part 23 formed in cooperation. Moreover, when the spoke cutting is completed, the part of the spoke exposed from the spoke fixing seat 213 at both ends is already very small, but since a gap can be formed between the two rotating seat bodies 211, the cut spoke can be conveniently taken out from the middle position, so as to realize efficient unloading of the cut spoke.

[0060] Further, with reference to Figure 3 and Figure 4Each rotating seat body 211 comprises a rotating disc 212 and a plurality of spoke fixing seats 213. The rotating disc 212 is a flat disc member, the center of which coincides with the first axis and is fixed on the rotating shaft through the mounting ring. A plurality of spoke fixing seats 213 are arranged on the circumferential edge of the rotating disc 212. The spoke fixing seats 213 are uniformly arranged on the circumferential edge of the rotating disc 212 at a predetermined angular interval. The number and positions of the spoke fixing seats 213 on the two rotating discs 212 correspond to each other. In each corresponding pair of spoke fixing seats 213, one part of the spoke fixing part 23 is arranged on each spoke fixing seat 213. When the two rotating discs 212 are installed on the rotating shaft, the parts of the spoke fixing part 23 on the two spoke fixing seats 213 cooperate with each other to form a complete spoke fixing part 23. Obviously, an embedding groove for embedding a part of the spoke is arranged on each spoke fixing seat 213. The embedding grooves on the two corresponding spoke fixing seats 213 are similar in structure and cooperate to form the spoke fixing part 23. An end opening 233 of the spoke fixing part 23 is formed at the outer end of each embedding groove. The end opening 233 allows the spoke to extend out of the spoke fixing part 23 after being embedded in the spoke fixing part 23, thereby facilitating the cutting of the extended part to make the length of the spoke meet the requirements. The size of the spoke fixing seat 213 in the first direction can be different from that of the rotating disc 212 in the first direction. A longer spoke fixing seat 213 can make the length of the arranged spoke fixing part 23 longer, ensuring that the spoke has a long enough part in contact with the spoke fixing part 23 after being embedded and fixed in the spoke fixing part 23, thereby improving the stability of the spoke during cutting.

[0061] Referring to Figure 4 In each spoke fixing part 23, a body segment 231 and a tightening segment 232 are included. The width of the body segment 231 is greater than that of the tightening segment 232, thereby better adapting to the corresponding shape of the spoke. Through the position of the tightening segment 232 on the spoke fixing part 23, the length of the part to be cut on the spoke to be cut can be directly defined when the spoke is correctly embedded and fixed in the spoke fixing part 23.

[0062] Further referring to Figure 1 and Figure 5The cutting assembly 30 includes two cutting devices 31 mounted on the frame 10 along a first direction; the cutting blades 32 of the cutting devices 31 rotate about a second axis in the first direction; the cutting blades 32 of the two cutting devices 31 are respectively located on the outer side of the corresponding side of the rotating base 21 in the first direction, and the cutting blades 32 overlap with the spoke fixing part 23 on the projection plane perpendicular to the first direction. In the cutting assembly 30, the cutting devices 31 are movably mounted on the frame 10 and are adapted to reciprocate along the first direction. The cutting assembly 30 also includes two second sliding devices 33; the second sliding device 33 includes a second driving cylinder 331 and a second mounting plate 332; the second driving cylinder 331 is fixedly mounted on the frame 10, and its output end is used to drive the second mounting plate 332 to reciprocate along the second direction; the second mounting plate 332 is fixedly connected to one of the cutting devices 31.

[0063] Specifically, refer to Figure 1 and Figure 5 The frame 10 is provided with a main support 17 extending vertically, located behind and higher than the spoke fixture 20. A cutting bracket 15 is bolted to the main support 17, and a second fixing plate 333 extending horizontally is bolted to the cutting bracket 15. Two second sliding devices 33 arranged horizontally are mounted on the second fixing plate 333. Each second sliding device 33 includes a second drive cylinder 331 and a second mounting plate 332. The second drive cylinder 331 is fixed to the second fixing plate 333, and its output end is fixed to the second mounting plate 332. A slide rail is provided on the second fixing plate 333 in the horizontal direction. The second mounting plate 332 is slidably mounted in the slide rail and can reciprocate horizontally on the slide rail under the drive of the second drive cylinder 331. The second drive cylinder 331 is controlled by an electrical control box 53. The second sliding device 33 allows the cutting device 31 to move back and forth along the first direction, which facilitates adjusting the cutting position according to the required spoke length and also allows for better cooperation with the spoke fixture 20.

[0064] The cutting device 31 comprises a cutting machine and a second connecting plate 311, the second connecting plate 311 is fixed on the corresponding second mounting plate 332 by bolts, and the cutting machine is fixedly installed on the second connecting plate 311. The cutting machine is provided with a cutting blade 32, which is used to cut the spoke fixed on the spoke jig 20. Among them, two cutting devices 31 are respectively located on the left and right sides of the spoke jig 20, the cutting blade 32 is located on the cutting device 31 closest to the corresponding side of the spoke jig 20, and the cutting blade 32 overlaps the rotation track of the spoke fixing part 23 in the projection plane perpendicular to the first direction, so that in the process of rotating the base 21, the spoke fixed in the spoke fixing part 23 will pass through the position where the cutting blade 32 is located, so that the end of the spoke will be cut by the cutting blade 32. It is easy to understand that the cutting blade 32 and the rotation track of the spoke fixing part 23 overlap in the projection plane, which means that when the spoke is fixed to the spoke fixing part 23, the rotation track of the spoke rotating with the rotating base 21 will pass through the position where the cutting blade 32 is located. When the spoke contacts the cutting blade 32, the rotating base 21 continues to rotate, the spoke is pressed by the cutting blade 32, and the cutting blade 32 rotates at high speed, thereby realizing the cutting of the spoke.

[0065] The above-mentioned spoke cutting device comprises a rack 10, a spoke jig 20 and a cutting assembly 30; wherein the spoke jig 20 comprises a rotating base 21 and a jig motor 22, the jig motor 22 can drive the rotating base 21 to rotate around the first axis, the spoke fixing part 23 is arranged on the rotating base 21, and the spoke to be cut can be fixed in the spoke fixing part 23 and rotate with the rotating base 21 around the first axis; the cutting assembly 30 comprises two cutting devices 31, the two cutting devices 31 are arranged along the first direction, and the cutting blades 32 of the two cutting devices 31 are respectively located on the two sides of the rotating base 21, wherein the cutting blade 32 overlaps the spoke fixing part 23 in the projection plane perpendicular to the first direction; through the structure design that the cutting blade 32 overlaps the spoke fixing part 23, when the spoke fixing part 23 is fixed with the spoke and the rotating base 21 is driven by the jig motor 22 to rotate, the two ends of the spoke in the spoke fixing part 23 will pass through the position where the cutting blade 32 is located and be cut by the cutting blade 32; the relative position of the two cutting blades 32 and the spoke fixing part 23 can be determined in advance, and the relative position of the two cutting blades 32 and the spoke fixing part 23 does not change in the cutting process, so that the spoke with the required length can be obtained repeatedly. The spoke cutting device fixes the spoke to the spoke fixing part 23 of the rotating base 21, makes the spoke fixing part 23 rotate with the rotating base 21, makes the spoke pass through the position where the cutting blade 32 of the cutting device 31 is located, and cuts the excess part of the spoke by the cutting blade 32, thereby completing the automatic cutting of the spoke. The spoke cutting device has the advantages of high efficiency, accurate cutting position and small cutting error.

[0066] Further, with reference to Figure 1 and Figure 6 The spoke cutting device further comprises a limiting assembly 40, which comprises two limiting devices 41 arranged on the frame 10 along the first direction; the limiting device 41 comprises a blocking strip 42, and the blocking strips 42 of the two limiting devices 41 are respectively located outside the corresponding side of the rotating base 21 along the first direction; the blocking strip 42 is provided with a limiting surface 43 in the form of an arc line matching the rotating track of the spoke fixing part 23 and on the projection surface, the position of the limiting surface 43 corresponds to the cutting blade 32 on the same side of the rotating base 21, and is configured to limit the spoke in the spoke fixing part 23 in the direction pointing to the first axis through the limiting surface 43 when the spoke fixing part 23 rotates to the position corresponding to the cutting blade 32. In the limiting assembly 40, the limiting device 41 is movably arranged on the frame 10 and is adapted to reciprocate along the first direction. The limiting assembly 40 further comprises two first sliding devices 44; the first sliding device 44 comprises a first driving air cylinder 441 and a first mounting plate 442; the first driving air cylinder 441 is fixedly arranged on the frame 10, and the output end thereof is used to drive the first mounting plate 442 to reciprocate along the first direction; the first mounting plate 442 is fixedly connected with the limiting device 41.

[0067] Specifically, with reference to Figure 6 A limiting support 16 is further fixedly arranged on the main support 17 by bolts, and a first fixing plate 443 extending along the left-right direction is fixedly arranged on the limiting support 16 by bolts, and the first fixing plate 443 is located behind the second fixing plate 333. Two first sliding devices 44 are arranged on the first fixing plate 443 along the left-right direction, each first sliding device 44 comprises a first driving air cylinder 441 and a first mounting plate 442, the first driving air cylinder 441 is fixedly connected with the first fixing plate 443, and the output end thereof is fixedly connected with the first mounting plate 442. A slide rail is arranged on the first fixing plate 443 along the left-right direction, and the first mounting plate 442 is slidingly arranged in the slide rail and can reciprocate along the left-right direction on the slide rail under the driving of the first driving air cylinder 441. The first driving air cylinder 441 is controlled to operate through the electric control box 53. Through the first sliding device 44, the limiting device 41 can reciprocate along the first direction, which facilitates the adjustment of the position of the limiting device 41 according to the length of the required spoke, and can also better cooperate with the spoke jig 20.

[0068] The limiting device 41 comprises an arc-shaped blocking strip 42, the lower side surface of the blocking strip 42 forms an arc-shaped limiting surface 43, the position and shape of the limiting surface 43 are just corresponding to the rotating track of the spoke fixing part 23 in the spoke jig 20, when the rotating base 21 rotates, the part of the spoke exposed from the spoke fixing seat 213 will be limited by the limiting surface 43. Specifically, since the spoke fixing part 23 is arranged in a groove shape, although this structure facilitates embedding and fixing the spoke into the spoke fixing part 23, when the cutting device 31 cuts the end part of the spoke, after the cutting blade 32 contacts the spoke, the spoke will jump, and then the cutting surface will be uneven. Therefore, in the technical solution, after the spoke enters the range of the limiting surface 43, the limiting surface 43 will limit the spoke in the first direction, the limiting here can be that the limiting surface 43 directly contacts the spoke, or there is a very small gap between the limiting surface 43 and the spoke, in both cases, the limiting surface 43 can prevent the spoke from jumping to a large extent during cutting, thereby effectively improving the problem of uneven cutting surface.

[0069] In addition, with reference to Figure 1 and Figure 2 The spoke cutting device further comprises a discharging plate 51, which is fixedly arranged on the frame 10 and extends downwardly and away from the rotating base 21, is located at a position downstream of the cutting device 31 in the rotating direction of the rotating base 21, and has a discharging protrusion 511 extending into the two rotating seat bodies 211 of the rotating base 21. During the rotation of the rotating base 21, the cut spoke will pass through the discharging protrusion 511, the discharging protrusion 511 will apply force to the middle position of the cut spoke and pry the cut spoke from the spoke fixing part 23, the spoke separated from the spoke fixing part 23 will move along the discharging plate 51, at this time, a material frame can be arranged at a proper position to collect the cut spoke.
